RODERICK w. HADDOOK, or INDEPENDENCE, oR EeoN;

Y ORE-SEPARATING DEVICE.

To all whom it may concern: Be it known that I, RODERICK W. Han- DOCK, a citizen of the United States, reslding at Independence, in the county of Polk and State of Oregon, have invented certain 1 I new and'useful'Improvements in Ore-Separatin .Devices, of whichthe following 1s a speci cation.

This" invention relates 'to ore separating devices, and more particularly, to an appa ratus operating by the improved dry process for separating minerals from their ores "Theinventi0n has more especial reference to a construction "of the character mentioned,whereby,gold, silver and other valuable minerals, may be separated from their ore by means of compressed air, which,-"is

deliverd oiito the ore as'the' same is fed into the separaton'the device being particularly adaptable for use in dry climates- 7 YMore' particularly, the presentinvention has referenceto: the novel construction and arrangement of the separator, the same com prising a tubular conveying tube, having a portion thereof formed in a zig-zag manner whereby, to cause'the minerals to be deflect:

i edinto suitable 'pockets'carrie'd by the con- 'veyer for'this purpose.

Another important characteristic of the invention, resides in the provision of an au xiliary pneumatic tube, which communicates with the mineral receiving: receptacle, for maintaining the same clear of waste. The invention also embraces a novel form of hopper, whereby the ore may be fed into the tubular conveyer, the same hopper being provided'with a cutofi for controlling the passage of the ore into the'conveyer andja screening member whereby the ore is fed into the tube in extremely fine particles, an

inclined baffle plate carried by the hopper and extending fora slight distance into the conveyer tube, thereby providing for means whereby the compressed air contained within thetube will be prevented from blowing ore upwardly as the same is delivered there- A into.

Among the aims and objectsof the invention may be recited, the provision ofa separato'r of the character mentioned, with a view to compactness, and inwhich the parts 1' are few, the construction simple, the costof production small, and tionfhigh. 1

Other and further improvements and novel details in the construction "and farefiiciency and operaunderstanding of the invention, should be considered in connection with the accom-- 1 spiecificat ion o f Letters lfatent V 2: Application filed ouster 5,1916. Serial No. 123,976. 3:

panying drawings, forming a part hereof and wherein-the preferred embodiment ofthe invention" isshown 'for the-purpose of,

illustration.

In the drawings separator," I

Fig. 3 a detail in section of one" of-the mineral and i Fig. 4 is'a vertical sectionhin fdetail through the'hopper. R ferringnow more particnlarly ito the drawings, wherein like reference numerals designate corresponding parts throughout;

receiving receptacles orr: pockets;

I. 5 V; i}; Figura -1 is 'a top planiof' myo p o remaining portion thereof. is so arranged as 1 1 to provide a plurality r of coiled :or 'zig-zag sections generally indicated as 5, -:'th'e; said sections being connected with each otherand with the portion 4 of the tubingbyi means of elbows 6, the endsof which may he pro= vided'with threads whichthread's anciengageable with complementalsportions arranged upon the opposite extremities. of said portions 5. The sections!) mayrbe and prefr erably are. constructed from apluraljity of separate pieces of piping, .the'adjacent ends of which are connected by unions 7 similar to those as designated by the numeral- 3.

An opening 8- is arranged within the straightaway 'pOI'tiOII'A; of the conveyer 1\ and hasarranged ther'eover a-hopp'erEQ, the upper portion of which is flared outwardly in the usual manner", as at 10 and-carries thereupon by means of a flange 11a wire mesh fabric 12, this fabric serving-as means for thoroughly sifting and pulverizirig f the ore as it-is fed into the conveyer 1. An'inclined baflie plater13 is afiixed" to one side .of

the' h'opp'er andfe ztends for a' slight"- distance downwardly into the straightaway portion 4 of the conveyer 1, thus, providing for means whereby the compressed air as contained within the conveyer will be prevented from blowing particles of the ore upwardly and out of the hopper, thus, eliminating possible waste. A closure plate 14 having a handle portion 15, is slidably arranged within the hopper 9 preferably adjacent the base portion of the flaring part 10 and is supported upon the wire mesh fabric 11. By this means, it is apparent, that when so desired, the operator may readily move the same forwardly, thereby closing the discharge opening of the hopper and preventing the passage of the ore into the conveyer, if so desired. It is of course, understood, that the hopper 9 is provided with a suitable opening, whereby the closure plate 14 may be received into the hopper.

In order to provide for means whereby the mineral may be separated from the ore as the same passes through the straightaway and zigzag portions of the conveyor 1, I arrange upon the bottom thereof, a series of depending tubular portions 16, the lower extremities of which are externally threaded as at 17 and adapted to have turn in engagement therewith, complementally threaded cap members 18, thus, forming eficient receptacles or pockets. Inclined battle plates 19 are formed upon one side of the tubular members 16 for a purpose as will be subsequently obvious. A shunt pipe 20, is engaged with the various tubular members 16 and communicates therewith, the remaining end of the same being inserted within the straightaway portion 4: of the conveyer 1, at a point beyond the hopper 9, as shown at 21. Thus, it will be apparent, that when compressed air is introduced into the inlet portion of the conveyor 1, a portion thereof will be shunted into the pipe 20 and delivered into the mineral receiving pockets, thus maintaining the same clear of waste matter, which might lodge therein, during the depositing of the mineral. The baflie plates 19 as carried by the tubular members 16, provide means whereby the minerals as contained therein will be prevented from passing into the conveyer 1, yet allowing the lighter particles or waste to be readily passed thereby and delivered into the conveyer, whereupon the same is instantane ously gathered up by the motive fluid and passed through the discharge end of the separator.

It should be noted that the balile plates 1 are formed above the pipe 20 and slant toward the ends of the pipe 20 entering the tubular members, thus causing an eddy of air under the baffle plates for removing the refuse particles from the tubular member. Also, the shortpipes 20 connecting the tubular members of the pipes of the zigzag section 5 extend at right-angles to each other.

In operation, the free end of the straightaway portion 1 is connected with a suitable source of compressed air, while the free end of the uppermost portion 5 is connected with a discharge conduit 22, thus when the ore is fed into the conveyer by means of the hopper 9; the same will be carried forwardly through the various sections of the said conveyer, and the mineral products as contained being of greater weight, will be gradually deposited within the various pockets as constituted by the tubular members 16, the heavier particles of the minerals being deposited within the first series of pockets, while the remaining or lighter products are gradually delivered into the remaining pockets. Such waste material as may accumulate within the pockets will be promptly ejected therefrom by means of'the shunt pipe 20, which pipe will deliver a blast of air into the said pockets, the'force of which is sufficient to dislodge the lighter matter. 1

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made 'as regards the construction herein disclosed, provided the means stated by any of the following claims or the equivalent of such states means be employed.

I therefore claim as my invention 1. In an ore separating device, the combination of a main piping, a plurality of sectional short pipings positioned in the same plane as the main piping, said short piping being substantially parallel, Ushaped elbows connected to the ends of said short piping, tubularmembers carried upon said short piping, short pipes connected to said tubular members, said short pipes extending at right-angles to each other, thus causing abrupt abutments for the particles of ore being drawn through said piping and pipes by air, so as to cause the minerals to be readily deposit-ed in said tubular members.

2. In an ore separator, the combination of a piping having a material delivery means, an air forcin'g'means communicating with said main piping, said piping having tubular members formed thereon and depending therebelow, a short pipe connected to said tubular members, one end of said last mentioned pipe projecting into said first men tioned pipe, baffle plates formed within said tubular members at points adjacent said first mentioned pipe, said baffle members extending downwardly into said tubular mem bers, thus causing particles of refuse to be blown from said tubular members into said mentioned pipe while allowing deposit of minerals to be retained in said tubular members.

3. In an ore separator, the combination of a main piping, tubular members extending below said main piping having a material delivery means, an air forcing means C0111- municating wit-h said main piping, caps detachably carried upon the lower ends of said tubular members, an auxiliary piping communicating with the interiors of said tubular members and being connected to said main pipe, thus causing air to be forced through said auxiliary pipe from said main pipe, bafile plates formed in said tubular members adjacent the upper ends thereof, said baffle plates being formed upon the tu-v bular members at sides opposite to the ends of said "auxiliary pipe tliereinto, said'bafile plates extending downwardly toward the entrance ends of the auxiliary pipe, thus causing the air injected into said tubular members to be agitated below said bafile plates for quickly and thoroughly removing refuse particles from said tubular members and directing the same into said main pipe.

In testimony whereof I aflix my signature in presence of two witnesses.
